Title: Improvements in or relating to lifting and hauling gear
IPC: B66D1/16
Filed: 1920-10-11
Abstract: 173,102. Padfield, W. W. Oct. 11, 1920. Drum or barrel winding- machines; driving-gear; selfsustaining gear; geared pulley-hoists.-In a haulage gear the driving-shaft 3, Fig. 3, is connected to the winding- shaft 8<a> through two-speed gear, one high speed through gears 2, 7, the other slow speed through gears 1, 4, and means are provided for clutching the winding-shaft to either gear according to the direction of rotation of the driving- shaft, and to the weight of the load. As shown in Fig. 3 four clutches are provided, a Weston clutch 15 for the low gear when lifting heavy loads, a ratchet mechanism 11, 12 - for-the high gear when lowering, a clutch 22 for the high gear when lifting light loads, and a clutch 24, 25 adapted to rotate the shaft 17 until the Weston clutch functions when lifting heavy loads. A pinion 18 screwed on the shaft 17 is normally prevented from actuating the Weston clutch by a spring 20, but when a heavy load is raised the spring is uncoiled and the pinion is rotated on the shaft 17 until the Weston clutch is applied. When lifting light loads the spring 20 unscrews the pinion 18, thereby releasing the Weston clutch and the clutch member 25 and permitting the clutch members 22, 21 to engage. When lowering, the ratchet mechanism 11, 12 forces the clutch 24, 25 to slip. As shown in Fig. 1, the low-gear 1, 4 for lifting is connected to the winding-drum 9 by a clutch 6, 10 when a heavy load is suspended from the hook 16, whilst the high gear 2, 7 is connected to the winding-shaft by a ratchet mechanism 11., 12 for lowering rapidly, the clutch then slipping. In a modification shown in Fig. 5, the driven wheels of the gears are mounted on the winding- shaft and the ratchet gear on the driving-shaft, the clutch 4, 34 being applied by the wheel 7, screwed on the shaft 8, when raising the load. When lowering, the wheel 2 is driven by the ratchet mechanism and unscrews the wheel 7. The wheels 7, 33 rotate at different speeds and, owing to the friction of a washer 35 between them, the wheel 32 must be driven to lower the load. If the driving power be removed the load is sustained by the friction. In further modifications the cone clutch 4, 34 is replaced by a Weston clutch and the shaft may then be screwed as before or fitted with cam-surfaces operating on the wheel 7 in a similar manner. The clutch 4, 34 may also be operated by mounting the winding- drum 9 on a screwed shaft, the wheel 7 then being keyed to the shaft. The winding-shaft may also be connected with screw-gear for raising sluices, &c.

Abstract: 985, 778. Counters; transfer mechanism. LANDIS & GYR Ltd. Aug. 1, 1962 [Aug. 9, 1961], No. 28802/61. Heading G4D. All except the lowest wheel of a counter are arranged to move rapidly from one digit to another by a transfer disc freely mounted on the wheelspindle, said disc being eccentrically-weighted and driven by the lowest wheel during part only of each revolution of the lowest wheel. The lowest wheel 2 is biased by a segment 10 from which projects a peg 8. The loosely-mounted transfer disc 12 is biased by anchor-shaped metal member 14 and carries also a peg 16. The lowest wheel 2 is driven continuously, e.g. by an electric meter, without effect on the transfer disc until peg 8 contacts peg 16. Then wheel 2 carries along the transfer disc against the action of gravity until the disc passes top dead centre when the transfer disc advances rapidly so actuating transfer pinion 20 and the next higher wheel one step.

Abstract: 1,001,228. Opening bales of and blending fibres. CROMPTON & KNOWLES CORPORATION. July 23, 1963 [Aug. 9, 1962], No. 29136/63. Headings D1F and D1N. Bale opening and fibre blending apparatus such as described in Specification 937,262 in which bales are reciprocated over rotary toothed members that pass through slots in a bridge member has the top of the bridge member located below the level of adjacent bale supporting surfaces. These adjacent supporting surfaces take the form of conveyer belts 20 which may be wide enough to carry two bales side by side and are so intermittently driven in reverse directions as to reciprocate the bales over toothed members or pluckers 22 which are partly covered by bridge members 60. Beneath the conveyer belts 20 is a further belt 24 on to which fibres plucked from the bales are thrown by doffers 23. This further belt normally carries the fibres forward in one direction only, but it may be reversed with bale movement, or remain stationary or creep during movement of the bales in one direction. Doffers 23 may have shields mounted to one side of them (Fig. 10 not shown) or may rotate in "doffer bowls" connected to a vacuum conduit or conduits (Figs. 11 and 13 not shown) In which case the further belt 24 is not required. In order that the bales may be firmly held during their movements a cage is mounted over the conveyers 20 to reciprocate in synchronism with the belts. The cage is preferably enclosed at the sides and top and is mounted on rollers 98 grooved to co-operate with guide rails 100. Preferably one end wall 33 of the cage is fixed and the other end wall 34, which may be formed of spaced vertical bars, may be adjustably positioned on racks 125. Various forms of hold-down platens 35 are described. These may provide dead weight loading or adjustable loading under the influence of hydraulic cylinders, such as 144. A single rigid platen may extend over all the bales being treated or articulated platens may be used that extend over a small member of bales. One of the side walls of the cage may be adjustable.

Filed: 1966-07-01
Abstract: 1,153,624. Cables. WESTERN ELECTRIC CO. Inc. 1 July, 1966 [2 July, 1965], No. 29580/66. Heading H1A. In the manufacture of a coaxial cable, plastics insulation on the central conductor is crosslinked, compressed in diameter, surrounded by a tubular conductor and heated so that it recovers its original dimensions and fits tightly within the tube. The insulation may be in the form of spaced polyethylene discs or a continuous expanded plastics sheath. The cross-linking may be effected by electron bombardment, ultra-violet light, or by a cross-linking agent such as dicumyl peroxide and may be effected before or after the insulation is applied to the central conductor. Thus for example the discs may be stamped from a cross-linked polyethylene sheet or as shown may be applied to the central conductor 12 and subsequently crosslinked in a Van de Graaff generator 22. The spacers are heat softened at 24, compressed in diameter at 26 and surrounded by a tube 41 formed from a copper ribbon 30 welded at 36, 40. The spacers are sufficiently compressed to allow the insertion of the welding tool 36 but expand to fit tightly within the tube when heated at 42. An outer insulating covering is extruded at 44, and this may be done at sufficiently high temperature to perform the function of the heater 42 which would be thus eliminated. The completed cable is drawn towards a take-up reel by a transport mechanism 10.

Abstract: 393,170. Variable-speed gearing. COLUCCI, G., 19A, Via Arco Mirelli, Naples, Italy. Oct. 24, 1932, No. 29756. [Class 80 (ii).] In variable-speed gearing, the variation is obtained by changing the ratio of the diameter of planetary rollers 6 to that of a non-rotary track 7 on which they run, the rollers 6 being supported on toggles which carry gear trains passing on the drive to a driven shaft. Toggle arms 2, 4, carried round by a driving-shaft 1 support the spindles 5 on which the rollers 6 are secured. Each spindle is connected by a train 8, 9, 10 to a sun gear 11 fast on the driven shaft 12. In forms shown in Figs. 5 and 6, the actual speed change is effected by separating pairs of track discs 15, 16 between which conical or rounded rollers 6 are pressed by centrifugal force. In a form shown in Fig. 7, the rollers 6 are rounded cones in pairs centrifugally expanded into contact with a pair of coned tracks 7 which are caused to approach one another to raise the speed of the shaft 12 by turning screws 22 in unison from a control gear 23. On the highest speed, rolling ceases, the rollers 6 being gripped solid between rings 27 loose within the non-rotary tracks 7 and spring-pressed taper sleeves 28 on the driving- shaft 1.
